A video widely circulated on Friday shows Israel’s far-right national security minister admonishing a Palestinian leader face-to-face inside a prison, saying Israel will confront anyone who acts against the country and “wipe them out.

Israel’s far-right security minister posted video footage of himself taunting the most high-profile Palestinian prisoner while visiting him in jail this week, in an encounter that has prompted outrage from supporters.

President Donald Trump has said little about his idea of relocating many of the Gaza Strip’s 2 million Palestinians to other countries since he stunned the world by announcing it in February. Israel has been in talks with African countries — many of which are themselves wracked by war and at risk of famine — about taking Palestinians in.
